Abstract

Study of the operating conditions of synchronous generator (SG) in parallel with the power grid and increasing their sustainability is currently an important task. For the purpose of increasing the stability of hydrogenerators, the automatic excitation control (AEC) is considered as an effective option. For calculation and analysis of electrical systems at steady-state and transient conditions, the MATLAB/Simulink simulation environment is used widely. Due to its possibilities to use functions "existing base", "blocks and models", as well as using the description of control elements, it is possible to analyze the operation condition of a synchronous hydrogenerator in the power grid under conditions of various short circuit (SC), taking into consideration the impact of strong actuated automatic excitation control (SA-AEC). The present article provides the results of transient stability analysis in rotor winding of Nurek HPP hydrogenerator. The results obtained allow to compare the transient phenomena in the rotor and the impact of SA-AEC at various SC.

考虑AEC的水轮发电机转子绕组在电网不同短路值下的暂态稳定性分析

研究同步发电机与电网并网的运行状态，提高其可持续性是当前的重要课题。为了提高水轮发电机的稳定性，自动励磁控制被认为是一种有效的选择。对于电力系统稳态和暂态工况的计算和分析，MATLAB/Simulink仿真环境被广泛使用。由于可以使用“既有基”、“块和模型”等功能，也可以使用控制元件的描述，因此可以在考虑强驱动自动励磁控制(SA-AEC)影响的情况下，分析电网中同步水轮发电机在各种短路(SC)条件下的运行状况。本文介绍了Nurek高压水轮发电机转子绕组暂态稳定性分析的结果。得到的结果可以比较转子中的瞬态现象和不同SC下SA-AEC的影响。
